Hear me, you heavens! Listen, earth!
For the Lord has spoken:
“I reared children and brought them up,
but they have rebelled against me. (Isaiah 1:2 NIV)

God opens with speaking not only to the Earth, where humans dwell, but also to the heavens. This is to emphasize His complete authority and dominion. Therefore the second half of the verse comes with a shock: that the children that this God has “reared” would dare to rebel against Him.
